GRAlN PRO-PORTIONER AND MIXER.

SPECIFICATION forming part of Letters Patent No. 574,270, dated December29, 1896.

Application filed July 23, 1896.

T 0 aZZ whom it may concern.-

Be it known that I, FRANKLIN S. BITTER, residing at Oheboygan, in thecounty of Cheboygan and State of Michigan, have invented a new andImproved Grain Proportioner and Mixer, of which the following is aspecification.

My invention is in the nature of a machine for measuring and mixing twoor more kinds of grain in any portions desired; and it has, primarily,for its object to provide a machine of this character of a very simpleand inexpensive nature in which the several parts are compactly arrangedand constructed to effectively serve for the intended purposes.

IVith other objects in view, which will hereinafter appear, theinvention consists in the peculiar and novel combination and arrangementof parts, such as will be first described in detail, and then bespecifically pointed out in the appended claims, reference being had tothe accompanying drawings, in which Figures 1 and 2 are perspectiveviews of my machine as seen from the opposite ends. Fig. 3 is aperspective view of the duplex n1easuring-cylinder. Fig. 4 is alongitudinal section of the same, taken practically on the line 4 4 ofFig. 5. Fig. 5 is a cross-section of the same, taken on the line 5 5 ofFig. 4; and Fig. 6 is a detail view of the registering mechanismhereinafter referred to.

In its practical construction my invention comprises a casinghaving aplurality of upper or feed compartments A A, an intermediate chamber A,in which revolves the measuringcylinder B, having a pluralityof-independent measuring -,compartments B B and a lower or mixingchamber 0, which is common to all the measuring-compartments and whichhas an outlet 0, as clearly shown in Fig. 4.

By referring now more particularly to Figs. 1 and 5 it will be noticedthe feed-compartment and the intermediate or cylinder-holding chamber Bare not in the same vertical alinement, while the mixing-compartment Ois directly under the said cylinder B.

The object in arranging the several parts in such a manner is that thecompartments B B have each a series of radially-disposed independentpockets Z) 17 having their sides and ends arranged parallel in thedirection of their depth, which are adapted to be moved in Serial No.600,271. (No model.)

communication with the feed-compartments A A and be filled as they passthereunder, and as such compartments b b are a width less than the widthof said pockets (see Fig. 5) and as the cylinder B in practice is slowlyrotated the solid part b of the cylinder forms ahopper-bottom inclinedin the direction of rotation of the cylinder, and thereby provides for apositive automatic feed of the grain into the pockets without danger ofclogging.

The pockets 1) b in length are preferably the length of thefeedcompartments A A, but may be of less length, if desired.

To regulate the quantity the different pockets may receive from thecompartments A A, such pockets have a series of slideways b b to receivethe removable slides b 17 To provide for readily changing such slideswhen desired, the ends of the casing have openings I)", having hingedcovers, as shown.

ing-compartment O, which consists of a shaft 6, extended at one end andprovided with a cog-gear F, held in mesh with large cog-wheel G on thecylinder-shaft B, which at the opposite end is provided with adrive-pulley 19 as shown.

On the shaft 6 is mounted a series of flights H, each having a threadedshank h, which is screwed into threaded sockets in the shaft, suchflights being arranged at alternate angles, as shown, so as to providefor a thorough mixing of the grain. The conveyer in practice, whileserving to feed the material to the discharge-opening, does not keep thechamber C clean of grain, but moves out a little every revolution,leaving balance to be thoroughly mixed before being discharged.

At one end the machine has a vertical casing I, in which is mounted aseries of dials J counting from units to ten thousand and connected inthe ordinary manner, as clearly shown in Fig. 6.

Within the casing I is pivotally supported a lever-arm K, the lower endof which extends through a slot a in the casing B (see dotted lines,Fig. 4) in the path of a projecting pin L, secured on the adjacent endof the cylinder B, as shown, whereby at each revolution of such cylinderthe lever will be swung and through the medium of the pawl it turn theunits-wheel one point.

E indicates a conveyer held within the mix- From the foregoingdescription, taken in :onnection with the accompanying drawings, it isthought the complete operation and advantages of my invention willreadily appear.

It will be seen that by adjusting the slides in the pockets of themembers B B diiferent quantities of different grain can be fed into themachine, which will be thoroughly mixed before being discharged.

By weighing theproduct of one revolution of the cylinder and afterwardmultiplying the number of revolutions made by the product of onerevolution it will give the amount in pounds of the grain mixed. \VhileI have shown the feed portion and the cylinder B provided with twocompartments, it is manifest the same may have three or more of suchcompartments.

Having thus described my invention, what 20 I claim, and desire tosecure by Letters Patent, is

1. The combination with the casing having a cylindrical portion A amixing-chamber F, at the bottom and a feed-hopper having a plurality ofcompartments, such hopper having its discharge-mouths arranged at oneside of the vertical axis of the cylindrical portion A of: the cylinderB, having a plurality of setsof pockets, having their months of a Widthless than the discharge-months of the hopper, said pockets having theirside and end walls arranged parallel in the direction of their depth,slide members adjustably held in such pockets, a rotary mixer andconveyor I'I, held in the mixing'chamber and means for operating thecylinder and conveyer substantiall y as shown and for the purposesdescribed.

2. The combination with the casing having feedways A and A, at the upperend, a collooting and mixing chamber at the lower end having a combinedmixing and conveyer mechanism, such casing having an intermediatecylindrical chamber, such chamber having covered openings in the ends,of the cylinder B, having two or more members B B each having a seriesof radial pockets provided with a series of slide-receiving grooves, andthe slide members Zr, for regulating the depth of the pockets, all beingarranged substantially as shown and for the purposes described.
